This study examined whether cigarette use is associated with sexual orientation among high school students.
Data were from a 2012 cross-sectional survey of 5994 students in grades 9, 10 and 12 attending public schools in Atlantic Canada. Multilevel logistic regression analysis was used to examine differences in cigarette use by sexual orientation.
Lesbian, gay and bisexual adolescents (LGB) reported higher prevalence (22%) of daily cigarette use compared with heterosexuals (11%). Multilevel logistic regression analysis, controlling for standard covariates, found that LGB adolescents were more likely to be daily smokers than non-LGB adolescents (odds ratio 2.00, 95% confidence interval 1.50-2.68). Bisexual adolescents were at least twice more likely to be a smoker compared with heterosexual adolescents.
Prevalence of cigarette use was significantly higher among LGB adolescent students. Our results join a growing body of evidence indicating that sexual minorities are at heightened risk of tobacco use. Smoking cessation measures that specifically target this group may be beneficial given that there is no one size fits all approach.
本研究探讨了高中生吸烟行为与性取向之间是否存在关联。
数据来源于2012年对加拿大新斯科舍省公立学校9、10和12年级的5994名学生进行的横断面调查。采用多水平逻辑回归分析来研究不同性取向学生在吸烟行为上的差异。
女同性恋、男同性恋和双性恋青少年（LGB）报告的每日吸烟率（22%）高于异性恋青少年（11%）。在控制了标准协变量的多水平逻辑回归分析中，发现LGB青少年比非LGB青少年更有可能成为每日吸烟者（优势比2.00，95%置信区间1.50 - 2.68）。双性恋青少年成为吸烟者的可能性至少是异性恋青少年的两倍。
LGB青少年学生中的吸烟率显著更高。我们的研究结果进一步证明了性少数群体面临更高的烟草使用风险。鉴于不存在适用于所有人的戒烟方法，专门针对该群体的戒烟措施可能会有所帮助。
